Swedish light tank invisible CV90120

Swedish light tank invisible CV90120
It so happened that in actual combat events is no room light tanks. This is due to the development of tools to support the armored units, such as armored personnel carriers, infantry fighting vehicles, self-propelled guns, etc. For more on this dilemma staring Swedes theater of operations which in some cases does not allow the languid technique.

Features of the implementation strategy of light tanks

Despite the fact that the Ministry of Defence of Sweden elected as a main battle tank Leopard 2 German tank, and the tank holds substitution S and Centurion for a new product of the German military industrialists, company Hagglunds continues the work on your own easy option tank. For this purpose, the standard used by experienced BMP CV 90, which at the present time has changed and received the title of CV90120-T.Rvenie professionals of this company run a tank in «series» just explained.

Here there are two reasons that explain the zeal Swedish engineers faster to finish upgrading the newest combat vehicle.

Firstly, the Armed Forces of the kingdom need to equip tanks korlandskie two teams that are deployed on the northern direction. Heavy tank Leopard 2 for this purpose is not appropriate, because in areas with inflated level of snow cover is necessary to ensure the application of light, walk-through tanks. With all of this very principle preservation firepower, ie tank gun should be more than 120 mm caliber.

In-2, a number of Asian, African and South American countries can enter the number of probable clientele, because the purchase of heavy and medium tanks is impractical because of the terrain and overhead project. Light tank cheaper, even more so if it corresponds to the category of weapons used by medium and languid tanks. For example, Malaysia first became interested in the development of the Swedish CV 90-120, but later was preferred tank PT-91 (Poland).

Project CV 90-120

In 1997 the company launched a Hagglunds project CV 90-120, in the implementation process which revealed that there was problem with the tower, which would correspond to the combat vehicle chassis by weight characteristics, all the proposed options tower compartment were bulky and heavy. In the end, as the tower «maison» was applied a modified tower complex products from IKV 91 with a gun caliber 105 mm, which was replaced by a 120 mm gun.

Technical Equipment

In the tank CV 90-120 used the same chassis as that of the basic version of the BMP C90, with all this added special stiffeners to keep the inertia of the mass shootings at 120 mm cannon. Because of this decreased slightly dynamic properties of the model.

V — shaped 8-cylinder engine Scania develops capacity of 640 liters. with., making light tanks successful power to weight ratio of the product. Aggregated with engine Perkins X box 300, which is the latest upgrade boxes Allison. Weighing in at 26 tons with ammunition product has a maximum speed of 70 km / h Suspension springs for road wheels provide uniform rassredotachivanie stress on the chassis. Geometric characteristics of caterpillars and bottom simplifies movement CV 90-120 on a snow cover. The driver is equipped with 3 telescopic devices for the review area, central of which can be replaced Mon AN / WS.

Configuration of the product casing rovnenkaya flat, adapted to the terrain. Radiators cooling of engine located right in the building, next to the exhaust pipe. It is made to reduce the ability to detect infrared emitters tank, reducing the coverage area of ​​the tank in the IR region. In the rear compartment foreseen place for ammunition. It also includes additional space for the fifth member of the team, also it can be used for reconnaissance of the area.

Firing tank capacity

Firing capacity of 120 mm tank gun presented reference OTAN, installed in the tower complex. Charging is at the left of the tower. It includes an automatic feeding system and ammunition loader. Magazine ammunition designed for 12 shots. The rest of the ammunition in the amount of 33 shots — Ammunition, storage — in the feed tank Automatic loading maintain rate of fire of 14 rounds per minute.

Tank gun made by RUAG de Thun (Sweden). This smoothbore gun fitted sliding brake parts and device for absorbing soot. The gun design was prepared in 70-ies of XX century under the earliest draft of the tank, which for some reason did not go in «series».

This gun was taken as the latest mock gun, to which was added brake sliding parts that played into the hands of designers tower complexes light type, because the returns become less noticeable.

Automatic operators targeting allow the tower to give the radial rotation with elevation angle guns from -8 ° to +22 °. Shooter provided device targeting UTAAS with a laser rangefinder and thermal imager. Tank commander uses daytime sights Thales Optronics with 3 fold increase (X1, 5; X6, X24)

Adaptiv cloaking system

The tank CV 90-120 for the first time, a system of concealment in the infrared spectrum. This development took place in the royal survey research institute, the copyright of this «cloaking technology» is the company Hagglunds.

External system components Adaptiv are hexagonal plates, which are assigned to her unusual appearance. With their tank not only becomes «invisible», and indicates instead imagers themselves in the wrong object, the phantom, «painted» with electronics.

This occurs followed properly. On these matrix component image transmitted truck, for example, in the infrared spectrum of a real solution. At a certain range of the Imager played this «phantom». In an emergency application of combat strike security sensors activates stealth system. The tank is covered by a cloud of spray splashing. Capacity of 300 liters. aerosol composition enough to hold the invisible screen over 2-minutes. The configuration of the tubes such that the sprayed liquid similarity with the effect of making the wavelength in the IR — spectrum, between 5 and 25 Mm, as a result of which the yield of the desired light absorption paradox.

According to the manager of the project in the company Hagglunds, infrared masking only the beginning, they are working to create a similar effect with radar systems

Electrical protection CV90120

Electrical protection CV90120 — Award of Celsius Tech et Grintek Avitronics. Laser sensors from the company Thales Optronics put crew aware of the target date, generating intelligence search. There is an option setting too much interference or physical destruction of targets. Radar brings information about the probability of detection of enemy targets by technical means or the shooting to defeat the enemy with the introduction of air or artillery.

Instrument Complex «starts» or aerosol masking produces shooting grenades posing special curtains.
